To all whom/kit may concern:

Be it known that I, GEORGE l?. FENNER,a citizen of theUnited States,residing at New Londoni n the county ofNew London and State ofConnecticut, have invented new and useful Improvements inPrinting-Presses, of which the following is a specification.

By means of this'inv'ention such operations as inking and feeding can besatisfactorily effected; and the invention'resides in certain novelfeatures of construction set forth in the following specication andclaims and illustrated in the annexed drawings, in which- Figure 1 is aside elevation of a press containing the invention. Fig. 2'is a planView of Fig. l. with parts broken. ai az, Fig. 1. Fig. l.

In the drawings is shown a type-bed f and impression-cylinder g, theoperation of which is known in the art. In Fig. 1 is indicated a rack 8,secured to the type-bedje, and the gear 9, alternately engaging the rackon opposite sides, causes this rack and bed to reciprocate. Traveling orreciprocating with this bed is a rack o., into which mesh the gears c,driving the ink-rollers la nearest the cylinder. Said gears c alsoengage the gear-Wheel b, or, rather, said gears being made in twosections c and c' the sections c engage such wheel b. This is soarranged as it has been found impossible or impractical to havethe gearsor gear-sections solid or integral and at the same time mesh into bothrack and gear, the rack cutting or forming a sort of chord along a sideor face of the gear, so that the distance between the gears measuredalong the rack varies or is shorter than the distance between saidpoints measured on an arc or on the circumference of the gear. Hence itis necessary to turn or' arrange the section c, which meshes into thegear bfa certain extent or fraction of a toothout of register with gearpart c, vwhich meshes into the rack. After these two sections are turneda trifle in relation toeach other they are fastened together, or theycould be cast in the desired relationship. On the hub of this wheel b orturning therewith is a smaller gear i, a similar gear being shown at thegear-wheel e, and these Fig. 4 is a section along Fig. 5 is a sectionalong y y,

Fig. 3 is an end elevation of Fig. l,

gears 7S carry or engage rack h. As such rack h reciprocates the gears band c rotate or oscillate in unison. The gears c are driven by the rackVa, the gears b by the gears c', while the gear t imparts motio'n to therack 7?., which in turn drives the gear e and'thesecond gear c', which,yoperates the fountain ink-rolls. The rackh is free to oscillateindependently of the bed. The gear e engages the gears d, driving theinkfrolls, which are over the table orlocated some distance away fromcyl inder g. These gears d are short or narrow that is, so arranged asto only mesh into gear e and allow rack h and vibrator-rack a to passthe face or sides of the gears without touching the same. a

In speakingof the gears c as driving the ink-rollers it may be notedthat such gears really mesh into the gears which drive or are mounted onthe ink-distributing rollers,which latter contact with the ink-rollersproper, and such ink-distributing rollers, in addition to rotary motion,are also normally given a transverse or axial motion.

The gears vl are shown smaller than gears l) e, so that the rack 7L runsat a dierent speed or more slowly than the bed.

Attached to the bed is shown what may betermed a register-rack, m,havinga joint or pivot connection n with the bed and held by spring o upagainst stop p. A gear-segment is shown at q on cylinder g. When thecylinder comes to the bed or these two parts come together, the yield orelasticity of spring o will allowthe rack to give or move so that theparts come together without so severe a shock as would otherwise occurif the parts were rigid or no provision made for yielding, especiallywhen running at high speed. The spring is made stiff enough to bring thecylinder and bed together in perfect register but flexible enough toreduce the severity of the blow. y

In the drawings is also shown an arrangement by which the tongues Z aremoved Without moving the feed-board r. The feedguides s are alsomovable. These parts are shown moved up and down by cams t, and thefeed-guides are constructed in such manner that the register of thesheet is not affected by the operation. This construction is adapted fora two-revolution press, so that the tongues Zwill be up when thecylinder IOS comes around the second time to deliver the sheet. Theraising of the tongues also raises the loose end of the feed-guide, andthe sheet is allowed to pass out or to the delivery without beingtouched or disturbed by the feedguide apparatus. On the second timearound when the grippers take a sheet the tongues are close down or tothe surface of the cylinder, so that the sheet can be taken perfectlysmooth by the grippers without wrinkling. The tongues Z can be suitablysupported or jointed at u to the board, and a screw or stop arrangemento can be provided or adjusted to limit the drop or swing of the tongues.This tongue Z is shown in Fig. l as part of a complete machine, but noclaim thereto is herein made.

In the drawings is shown a ductor-roller l, Fig. l, for taking ink fromthe fountain 2 or its roller 3 and applying the same to theinkdistributing roller 4,which in turn applies the same to theinking-rollers k away from cylinder g. These rolls 7e apply the ink tothe table or ink-slab, which forms, as it were, the rearward extensionof the type-bed f, and as this bed runs toward cylinder g, so that theink-slab portion contacts with ink-rollers 7c near cylinder g, theselatter rollers are inked, so as in turn to apply the ink to the typeportion of the bed or table f. This ductor-roller 1 is applied above theink table or bed fand is kept permanently out of contact therewith andis timed to swing to or contact with the Vibrating or ink-distributingroller 4, while the latter is practically at rest or has temporarilystopped rotating or moving. By this arrangement the backlash or rattleat the gears of the ink-distributing roller, caused by a ductor-rollercontacting with an ink-distributing roller while in motion, is avoided,thus preventing not onlynoise,which is objectionable, but alsopreventing the rollers or their bearings from working loose. Thisductorroller can be mounted in a suitable way for vibrating orcontacting with the ink -font roller and the ink distributing roller. Aswinging arm or lever 5 is shown supporting the ductor-roller, which arm5 is linked to or actuated by lever 6 and cam 7. This ductorroller beingbrought into contact with the inkdistributing roller 4 when practicallyat rest or at the beginning of a series of revolutions in one directionof said roller 4, the ink will be thoroughly or uniformly distributedabout the entire circumference of the ductor-roller and of the rollers 4and 7a and also of the inkbed, so that when the latter moves to contactwith rollers 7.: the ink.v is uniformly distributed to insuresatisfactory inking of all the type. The ductor roller l or its shaft ormounting being applied above the ink table or bed f allows readymounting and dismounting of and access to the ductor-roller and leaves aclearance or space between the inkfountain, the inking-rollers, and theink table or slab.

In stating that the ductor-roller is made to contact with theink-distributing roller when practically at rest it is understood thatthe vibrator-roll need not be absolutely still, but practically at thepoint to where it comes to rest. As the vibrating roll reverses almostinstantly, it might be a little difficult to bring these two rollstogether exactly at this point of absolute rest.

As to the purpose and advantage of this construction and of the functionsecured by this invention it may be stated that the gearing for drivingthe table ink-rollers is simple, noiseless in its action, that there arefew working joints between bed and table ink-rollers, and that there isno liability to get out of order. The ink-carrying roll, which swingsbetween the fountain and the first vibrating roll, is brought intocontact with roller 4 when at rest. This prevents noise which would becaused by starting the carrying-roll quickly at high speed.

What I claim as new, and desire to secure by Letters Patent, is-
